Ultimate-n 6300AGN Pci-e Wirless WiFi Card USE for Lenovo THINKPAD/HP Intel 6300AGN Card 802.11a/b/g/n 2.4 Ghz and 5.0 Ghz Spectra 572511-001 Fru:60Y3233

With my Lenovo T530, this could not have gone more smoothly. I can finally take advantage of the full capability of my internet speed, as I went from an average of 40 Mbps with my original card, which could only connect on 2.4 Ghz, to an average of 150 Mbps on 5 Ghz with the 6300AGN. Also, here's some info that might be useful: with the three wire connection on my T530 (and I'm assuming all Lenovo computers that use the 6300AGN), the gray wire goes to TR1 (MAIN), black goes to TR2 (AUX), and white goes to TR3 (RO). Laslty, be sure to get the most recent driver software directly from the Intel site. As of this review's date, the most recent update for the 6300AGN is the version dated 10/1/2017. I'd insert a link here, but Amazon doesn't allow it, so just Google "Intel 6300AGN driver" and it should come up as one of the first results.

Tricky install, but ultimately successful... so read this post for helpful info. I did a ton of research on this before buying to make sure it was compatible (whitelisted). And it works great on my T430 running Windows 7 Pro. My Internet router clocks 300+ up/down on my Fiber Internet 300. For my previous factory wifi card on T430, I was getting only 30-50 MB down/up (sometimes as low as 10 mbps). After installing the Intel Ultimate-n 6300AGN, my speed is 200 MB down/up. It's a cheap investment as long as you don't mess up your laptop during the install. YouTube has a great video that shows exactly how to get to the wifi card (but shows a card with only 2 antennas) . Lenovo site shows what to look for with both 2 and 3 antenna cards. The factory wifi card has only 2 antennas. Intel Ultimate-n 6300AGN has 3 antennas. In the T430, the 3rd antenna wire is there... it's just tucked away unused. Installing the hardware wasn't difficult (but I've been down in the guts of my T430 before). My only problem was that Windows 7 did not recognize the new card and did not install the drivers when I booted up. I used Device Manager to search for new hardware, and it definitely found "something", but Windows didn't know what it was. I tried Windows update device drivers, and obviously that didn't work. I also downloaded the Intel Driver & Support Assistant didn't detect the wifi card either. Finally, I tried using Lenovo ThinkVantage System Update and it worked!!! And the drivers installed were the latest ones available from Intel (2015). During my driver challenge, I was directly plugged into my internet router in order to get out to the internet... so you better make sure that works before messing with your wifi card. FYI - A previous posts said they didn't have any problems with Windows recognizing the new card and installing the correct drivers, so maybe the person was on Windows 10 and it doesn't have this problem.

Installation was pretty smooth. After swapping out the old card, I attempted to install the drivers. The installation process seemed to lag for a while, and I forced a system shutdown. I then started the machine back up and did a full reboot (Windows 10 only does a partial reboot unless you choose to restart). Upon restarting, the card was working. I then went through the installation process again, and it completed in short order. Perhaps I was just being impatient during the first installation attempt, or perhaps there was some hangup. Either way, it ended up working fine.The card that came with my Thinkpad T530 would stop working intermittently. Upon doing some research, I found that this was a known problem. The new card seems to be faster, although speed was never really the issue (the issue was reliability). If I have any issues with this card, I'll update my review. For now, this card is recommended.

Installed this in my Thinkpad X230, running Debian. This is the second one of these I've tried. The first one had a problem where it would intermittently disconnect and re-connect. So I returned it, and was sent this one. This one works OK, if I am within 10 feet of my access point. Beyond that, the connection starts getting very slow. So the range is very short. It is not nearly as good as the original wifi card that came with the laptop. One interesting quirk with this card is that when I turn off Bluetooth, the wifi light blinks.

Used it to upgrade an old Lenovo T420 Laptop to use it on the 5ghz WiFi band.Note to others who are thinking about upgrading from a 2.4ghz only adaptor to a dual 2.4/5.0 adaptor, make sure your laptop has the 3 WiFi antenna wires required for the 5.0ghz WiFi band. The third wire will likely have an small insulator covering it's connector. I have no idea when Lenovo/IBM started installing the 3 antenna setup for 5.0ghz. I know my very old Dell only had 2 antennas and even if I could have found a 2.4/5.0ghz adaptor that would have fit in it, it wouldn't have worked very well, if at all, without the 3rd antenna.

I bought a Refurb T520 online, turns out it had no wifi card installed. After tying a couple that turned out to be whitelisted (wouldn't boot), I gave up and went with an externa USB style that worked. Since I've always wanted to get the internal wifi working, I tried one more time with this... Bingo! Booted up and worked!

Although this card is rather outdated, it still performed excellently in the application I used it for..the additional antenna allowed for an improved connection between my router and computer, so I am having less signal loss...nice product.

I installed this because I just playing around with a ThinkPad T420 and wanted to max out a base model. This card worked like a champ. This card uses 3 antennas and the 3rd one is already in there tucked back slightly, plug and play for the most part!
